LAND-ROLLER.

Specification of Letters Patent.

Patented April 20, 1909.

. Application filed July 6, 1908. ScrialNo. 442,045.

Land-Rollers; and I do hereby declare the,

following to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertainstomake and use the same.

My invention relates to improvements in land rollers, and moreparticularly to reversible scrapers for reversible land rollers, and itsobject is to provide a reversible scraper to engage the roller andremove adhering material therefrom when the roller revolves in eitherdirection, and to provide the device with various new and usefulfeatures hereinafter more fully described and particularly pointed outin the claims.

The device consists essentially of a flat plate journaled in the framenear the roller adapted to alternately engage the respective edges ofthe plate with the surface of the roller, and a weighted leveradjustably attached to the late and adapted to alternately and yielingly maintain contact of the respective edges of the plate with theroller, and in various details of construction and arrangement, as willmore fully appear by reference to the accompanying drawings in which;

Figure 1 shows a portion of a roller with my device attached; Fig. 2 adetail partially in vertical section, and adjusted with the lower edgeof the plate in contact with the roller; Fig. 3 the same adjusted out ofactionand with the roller omitted; and Fig. 4 an elevation at rightangles to Fig. 3.

Like numbers refer to like parts in all of the figures.

1 represents the roller and 2 the frame of a land roller such as shownin my Patent No. 894,430, granted July 28, 1908, on land rollers.

3 is a rock shaft journaled in the frame near the outer surface of theroller and spaced apart therefrom, said shaft having a flattened middleportion to which is attached a flat steel plate 4 having its respectiveedges projecting above and below the shaft a suitable distance toalternately engage the surface of the roller as the shaft is oscillatedabout its axis To shift this shaft and yieldingly hold the edge of theplate in contact with the roller, I provide an upwardly projecting arm 5fixed on the shaft and carrying a slotted segment 6. Pivoted to this armnear the shaft 3 is a lever 7 extending through the slot of the segmentand traversing the same, on the upper end of which lever is adjustablymounted a weight 8;

To hold the arm 5 in vertical position with the plate 4 vertical and outof contact with the roller, I provide a sliding bolt 9 mounted on theframe 2 and adapted to engage an opening 10 in the arm, and thus lockthe same in vertical position.

In order to engage the l{plate 4 at pro er angle for scraping the su aceof the ro er, the shaft 3 has but a limited movement about its axis andis close to the roller. The slotted segment 6 afiords a greater angularmovement to the lever 7 than has the shaft and plate, whereby the levershifts to a greater distance from the vertical position than does thearm. The weight is thus rendered more effective, and will notunintentionally shift from side to side.

When the roller is reversed in operation, the position of the weight andlever 7 is re versed in the segment and this change re versesthe plate 4with its other edge in contact with the roller, and thus properlyadjusts it for the reversed movement of the roller. When locked invertical position by the bolt 9, the plate is out of contact with theroller and inoperative.

What I claim is 1. A land roller, comprising a roller, 2. frame in whichthe roller is rotative, a plate journaled in the frame and ada ted toalternately engage its respective e ges with the surface of the roller,and a weight connected to the plate and shiftable to opposite sides ofthe vertical plane of the pivots of the plates.

2. A land roller, comprising a roller, a frame in which the roller isrotative, a plate journaled in the frame and ada ted to alternatelyengage its respective e ges with the roller, an upwardly projectinglever connected to the plate and shiftable to oppositely inclinedpositions, and a weight attached to the lever.

3. A land roller, comprising a roller, 2. frame in which the roller isrotative, a rock shaft journaled in the frame and extending near thesurface of the roller and spaced apart therefrom, a plate attached tothe rock shaft and alternately engaging the roller at its respectiveedges, an arm fixed on the shaft and extending u ward there from, asegment on the arm, a ever pivoted near the shaft and traversing thesegment, and a weight attached to the lever.

4. A land roller, comprising a roller, a frame in which the roller isrotative, a rock shaft journaled in the frame, a plate attached to theshaft and alternately engaging the roller at its respective edges, anarm fixed on the shaft and extending upward therefrom, a bolt engagingthe arm to lock the same in vertical position, a segment on the arm, alever pivoted on the arm near the shaft and traversing the segment, anda weight attached to the lever.

in a land roller, the combination of a roller, a frame in which theroller is wrotati've,

.a rock shaft journaled in the frame and h aving a flattened portionopposite the roller, a

fiat plate attached to said portion and alterto the arm near the shaftand traversing the slot in the segment, a weight 011 the lever, and aslidable bolt on the frame and engaging the opening in the arm to lockthe arm in vertical position.

In testimony whereof I affix my signature in presence of two witnesses.
